i added more to the main menu, as it has a settings menu now, that stores its files with json. i also changed the font to atkinson hyperlegible and made a BaseMenu class that takes care of the screen scaling for menus.
i also refactored the project folder structure to make it more organized.
WallManager binds to the BodyEntered signal on the Area2D class and
detects if the body that entered the area is the ball class, and if it
is, it will reset the ball to its starting position. right now, theres
no scoring system. this will be added later.
